Um? this would forbid to use any other port than 3260 for any of the
protocols stated above. That doesn't make sense neither for iSCSI nor
for the other ones.
The code should make sure that the port is in range <0,65536> and don't
force to use a certain port. Ohterwise we wouldn't need a port field.
How about make a check for every protocols above, eg FTP, HTTP. As
known, different protocol use certain port, if just make sure
They use certain ports as a default. That doesn't mean the admin can't
configure to run the service at a different port.
Yes, I see.
the port is in range <0.65535>, error info may be like

You didn't understand the error message apparently. The message says
that the FTP backend in qemu is supported only with read-only disks, not
that port "100" is invalid.
I misunderstand the error info. Thanks for explanation
